Application filed February 6, 1914. Serial No. 817,058.

To aZZ whom it may concern Be it known that I, Josurn F. OBORNY, a citizen of the United States, residing at Bison, in the county of Bush and State of Kansas, have invented certain new and useful Improvements in Automatic Fasteners for Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is the provision of an improved spring actuated door latch or bolt of simple and efficient construction and inexpensive to manufacture.

Another object is to provide simple and ellicient means for retainingthe bolt in inoperative position.

W'ith these and other objects in view, the invention consists in the novel construction, arrangement and combination of parts to be hereinafter clearly described, reference being had to the accompanying drawing, in which,

Figure 1 represents a front elevation of the latch applied to use. Fig. 2 represents a longitudinal sectional view through the latch and cooperating parts, and, Fig. 3 represents a transverse sectional view on the line 33 of Fig. 2.

Referring to the drawing in detail wherein similar reference numerals designate cor responding parts throughout the several views, the numeral 5 indicates the base plate having the opposite ends 6 and 7 turned outwardly at right angles thereto and aperturecl to receive the bolt 8 which is slidably mounted therethrough. The plate 5 is adapted to be secured by suitable screws 9 to a door 10 at a point upon the in or outside thereof conveniently accessible. One end of the bolt 8 is turned at right angles and formed at its end with a handle knob 11. The opposite end of the bolt 8 is adapted to be seated within an aperture 12 formed in a keeper 13 having one end turned as at ll to provide a deflecting plate 14- for auto matically retracting the bolt 8 as the door 10 is moved to closed position.

The bolt 8 is normally held in extended or locked position by a spring 15 disposed between the turned end 7 of the base plate 5 and a washer 16 positioned against a split key or cotter pin 17. A second cotter pin 17 is positioned through the bolt 8 in spaced relation to the first pin and a pair of washcrs 16 are interposed on said bolt between said pins. An operating lever 18 is positioned through a suitable opening 19 in the base plate 5 and is formed at one end with a suitable handle or knob, and at the opposite end with an aperture rotatably receiw ing the bolt Sand positioned between the pair of washers 17. 'i

It will be understood that a suitable opening is formed in the door 10 registering with the opening 19 in the base plate 5 for receiving the actuating handle 18.

The turned end 7 is curved outwardly from the body 5 at 20 and is notched as at 21. To look the bolt 8 in inoperative position, as shown in Fig. 2, the same is rotated a quarter revolution and seated in the notch or recess 21.

It will be understood that the bolt 8 is freely rotatable with the apertured end of the actuating or operating lever 18 and that the latter is adapted for sliding the bolt 8 to open the door 10.

Apertures 22 are formed through the turned ends 7 and 11 and are adapted to receive a suitable padlock or other securing means for locking the bolt 8 in locked position.

A suitable retaining tongue is preferably formed at the end 7 of the base plate 5 and extended for a distance parallel therewith and turned outwardly in parallel planes with the turned end 7 thereof. This extension is adapted to receive the turned end 11 of the bolt 8 for securing the latter in locked or extended position.

What I claim is 1. In a device of the character described, a base plate having outwardly bent end portions and secured to one side of a movable closure, a keeper secured to the embrasure of said closure in alinement with said base plate, a bolt slidably and rotatably mounted in said end portions and capable of engagement with said keeper resilient means for normally holding said bolt in engagement with said keeper, means manually operable from the opposite side of said enclosure to withdraw said bolt from such engagement, similar means also associated with said bolt and operable from the first said side of said movable closure for also with drawing said bolt from engagement with said keeper and means coacting with said last mentioned means for maintaining the bolt in its withdrawn position.

2. In a device of the character described, a base plate secured to a movable closure outwardly turned and apertured ends projecting therefrom, one of said ends being curved and notched upon its outer edge, a bolt adapted for rotational and longitudinal movement through said apertured ends, an angular extension formed upon one of the ends of said bolt, an apertured keeper secured in alinement to said base plate and to the embrasure of said movable closure means for normally holding said bolt in engagement with said apertured keeper, manually operable means for withdrawing said bolt from such engagement and means associated with said a'ngular extension and said curved and notched end for continuously holding said bolt from said engagement.

3. In a device of the character described, a base plate secured to one side of'a movable closure outwardly turned end portions formed upon said base plate, a keeper secured upon the embrasure of said movable Copies of this patent may be obtained for closure in alinement with said base plate, a bolt slidably mounted in said end portions and capable of engagement with said keeper means associated with said bolt for holding the same normally in engagement with said keeper means manually operable from the opposite side of said closure to withdraw said bolt from said keeper, means formed on the extremity of said bolt coacting with one of said outwar ly turned end portions to maintain said bolt in its withdrawn position, and means associated with said manually operable means for prevent- Josnrnr.
